Adult Mosquitoes
The destruction of mosquitoes in tents, huts, etc., has always been recognised as a valuable measure of malaria control. At the beginning a kerosene pyrethrum fly spray was used and was effective, but supplies were rarely adequate and the flit guns supplied were far too flimsy for service conditions. Later American freon pyrethrum aerosol bombs became available, and these were most effective and economical in space and weight.
